Committed, THANKS.

There are some small fixes I test right now. Pointed out by Andrew P.

(multilib, which does not exist anymore, install path of libgcc_s.dylib)

Regarding the libjava and libstdc++ people, I apologize not having sent 
the patch to these lists. I made the assumption that most of them read 
the gcc-patches too.
Also, I only modified some *.exp in libjava and libstdc++. I hope they 
are ok. Otherwise I immediately revert.

Thank you again.

Andreas

Ready to be flamed :)
